I would say ZERO since its a sattelite that is build to pick up radio and other electronic signals. Or did you think they managed to throw a huge cam in it as well?
for satellite images where you can see stuff on the ground, you need Low Earth orbit satellites.
You use geostationary positioned further out in space when you want to measure radiosignals, weather, heat ect ect ect. But optical cameras NEED to be low Earth orbiting
